Ford Mustang enthusiasts have been begging for an EcoBoost engine for some time. Ford gladly answered this wish in the new S550 Mustang platform. For the first time in the Stang’s 50 year history, the 2015 Mustang will feature Ford’s super impressive EcoBoost power plant. The EcoBoost engine that will power the new Stang will be the 2.3L in-line four cylinder engine. Fox Body Mustang fans don’t get to nostalgic as you reminisce about the “old days” of the turbocharged 2.3L SVO Mustang.

The 2.3L EcoBoost engine is estimated to make an impressive 305 horsepower and 300 ft-lbs of torque. The amazing power will all be made while still taking it easy on your fuel consumption. So you get turbocharger performance and fuel economy – hard to beat combination right?
